<p>
A GtkPrintContext encapsulates context information that is required when
drawing pages for printing, such as the cairo context and important
parameters like page size and resolution. It also lets you easily
create <a
href="/usr/share/gtk-doc/html/pango/pango-Layout-Objects.html#PangoLayout"
><span class="type">PangoLayout</span></a> and <a
href="/usr/share/gtk-doc/html/pango/pango-Text-Processing.html#PangoContext"
><span class="type">PangoContext</span></a> objects that match the font metrics
of the cairo surface.
</p>
<p>
GtkPrintContext objects gets passed to the ::begin-print, ::end-print,
::request-page-setup and ::draw-page signals on the <a class="link" href="gtk-High-level-Printing-API.html#GtkPrintOperation"><span class="type">GtkPrintOperation</span></a>.
